If the battery charging circuit is ok then it might be a problem with some part of the electricals. There could be a short circuit or some such thing which is discharging the battery.

As the battery has just been changed, and assuming that it is indeed being charged as it should, then it has to be an electrical drain on the battery which causes it to go flat (when the engine is off).

One thing you can do is check electrical connections and make sure everything is tight and secure. I've heard of batteries and starter motors being changed when in the end the problem was only a loose bolt attaching the battery ground cable to the frame (or engine block)!!

Then you can do a few tests yourself if you have a Digital Voltmeter. Alternatively you can take your bike back to the mechanic who should really investigate the problem a little deeper as it is clear the battery isn't the problem. Good luck

hummmm

may be some wiring problems , have you fitted any extra horn or light or central lock or some thing like that on your bike .

just check all complete wiring from a good macanic . after that may be your problem get solved ........

funnily, even i am having the same problem with my bike... and the strange part is that if i disconnect the horns, the battery retains the charge for about 6 days. but if i connect the horn again, the battery dies within an hour..

the wiring on my bike is ok as far as i have checked. this weekend, i will be taking it to my mechanic. maybe i am having a shorting somewhere on my bike.. will try the voltmeter method today though...

Isn't this thread at the wrong place?
